| 摘 要： | 近年来北京雾霾天气频发,空气颗粒物聚集是导致雾霾天气发生的主要原因之一.作为一种重要的空气颗粒物,生物气溶胶对人体健康存在危害.本研究调查了雾霾天气时,生物气溶胶浓度和粒径分布规律;对其同空气质量指数PM2.5(AQI),环境温度和湿度间的Spearman’s相关性进行了研究;分析了冬夏两季重度雾霾天气时,生物气溶胶粒径分布规律.结果表明,生物气溶胶浓度与PM2.5(AQI)呈负相关,与环境温度呈正相关.环境湿度与细菌气溶胶浓度呈负相关而与真菌气溶胶浓度呈正相关.在冬季,最大浓度细菌和真菌气溶胶分别在4.5~7.0μm和2.1~3.3μm粒径范围内检测到,而夏季最高浓度细菌和真菌气溶胶均分布在3.3~4.5μm范围内.本研究结果将为不同雾霾天气下,评价生物气溶胶对人类健康造成的危害提供基础数据. |
